Objective:
To investigate the health-seeking delay in tuberculosis among school students in Yining City, Xinjiang Uygur Autonomous Region from 2009 to 2020, and analyze the influencing factors, so as to provide the evidence for reducing the health-seeking delay in tuberculosis among students in Yining City.
Methods:
The demographic features and diagnosis of students with tuberculosis in Yining City from 2009 to 2020 were retrieved from the Tuberculosis Management Information System of the Chinese Disease Control and Prevention Information System, and the factors affecting the health-seeking delay in tuberculosis were identified using the multivariable logistic regression analysis.
Results:
A total of 443 students with tuberculosis were reported in Yining City from 2009 to 2020, including 209 boys and 234 girls, with a male/female ratio of 1∶1.12. There were 29 primary school students ( 6.55% ), 81 junior high school students ( 18.28% ), 187 high school students ( 42.21% ) and 146 college students ( 32.96% ) reporting tuberculosis, and 394 cases ( 88.94% ) had locally registered residence. There were 287 students with health-seeking delay in tuberculosis ( 64.79% ), and the median duration of health-seeking delay was 35 ( interquartile range, 33 ) days. Multivariable logistic regression analysis showed that registered residence ( local, OR=1.899, 95%CI: 1.004-3.591 ) and origin of tuberculosis patients ( clinical consultation, OR=3.448, 95%CI: 1.755-6.775; recommendation for symptoms, OR=3.215, 95%CI: 1.161-8.900; tracking, OR=2.415, 95%CI: 1.269-4.596 ) and diagnostic results ( positive sputum smears, OR=3.081, 95%CI: 1.710-5.551 ) statistically correlated with health-seeking delay among students with tuberculosis.
Conclusions
The proportion of health-seeking delay in tuberculosis was high among students in Yining City from 2009 to 2020; registered residence, origin of tuberculosis patients and diagnostic results were associated.

Objective:
To investigate the prevalence and influencing factors of latent tuberculosis infection (LTBI) among freshmen in a vocational college in Xinjiang Uygur Autonomous Region, so as to provide insights into tuberculosis control in vocational colleges.
Methods :
All freshmen enrolled in a vocational college in Xinjiang Uygur Autonomous Region in 2020 were recruited and participants' demographics, life style, history of tuberculosis contacts, frequency of ventilation and disinfection in dormitories and classrooms and awareness of core tuberculosis control knowledge were collected through questionnaire surveys. LTBI was detected among freshmen by means of purified protein derivative test (PPD skin test) and chest X-ray scans, and the factors affecting LTBI were identified using a multivariable logistic regression model.
Results:
A total of 5 463 freshmen were screened for LTBI, with a screening rate of 100.00%, and the participants included 2 151 men and 3 312 women, with a male/female ratio of 0.65︰1, and had a mean age of (16.83±1.05) years. A total of 388 freshmen were detected with LTBI, with a detection rate of 7.10%, and no active pulmonary tuberculosis was detected. The prevalence of LTBI was 9.44% in men and 5.59% in women. Multivariable logistic regression analysis identified males (OR=1.587, 95%CI: 1.281-1.965), smoking (OR=2.108, 95%CI: 1.355-3.278) and a history of tuberculosis of families (OR=2.851, 95%CI: 1.615-5.034) as risk factors for LTBI among freshmen, and knowing core tuberculosis control knowledge as a protective factor of LTBI among freshmen (OR=0.276, 95%CI: 0.218-0.350).
Conclusions
The risk of LTBI was associated with gender, smoking, history of tuberculosis of families and understanding of the core tuberculosis control knowledge among freshmen in this vocational college in Xinjiang Uygur Autonomous Region. Health education about the core tuberculosis control knowledge is recommended to be reinforced among students in vocational colleges in Xinjiang Uygur Autonomous Region.

Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and is the fourth-leading cause of cancer-related deaths worldwide. HCC is refractory to many standard cancer treatments and the prognosis is often poor, highlighting a pressing need to identify biomarkers of aggressiveness and potential targets for future treatments. Kinesin family member 2C (KIF2C) is reported to be highly expressed in several human tumors. Nevertheless, the molecular mechanisms underlying the role of KIF2C in tumor development and progression have not been investigated. In this study, we found that KIF2C expression was significantly upregulated in HCC, and that KIF2C up-regulation was associated with a poor prognosis. Utilizing both gain and loss of function assays, we showed that KIF2C promoted HCC cell proliferation, migration, invasion, and metastasis both in vitro and in vivo. Mechanistically, we identified TBC1D7 as a binding partner of KIF2C, and this interaction disrupts the formation of the TSC complex, resulting in the enhancement of mammalian target of rapamycin complex1 (mTORC1) signal transduction. Additionally, we found that KIF2C is a direct target of the Wnt/β-catenin pathway, and acts as a key factor in mediating the crosstalk between Wnt/β-catenin and mTORC1 signaling. Thus, the results of our study establish a link between Wnt/β-catenin and mTORC1 signaling, which highlights the potential of KIF2C as a therapeutic target for the treatment of HCC.
